  • Twenty three species belonging to ten genera collected from Qinjia County in Debao District of Guangxi are described in this paper. Including three new species (Plectospathodus duowenensis;Polygnathus debaoensis and Polygnathus qinjaensis) and four uncertain species. Four zones of Polygnathus (P.dehiscens; P. perbonus; P. inversus; P. serotinus) are found and the the writer suggests that the Qinjia Formation and Debao Formation to be Lower and Middle Devonian in age. The conodonts zones are correlated with related strata of Western Europe and North America. Meanwhile, preliminary investigation on Devonian conodonts and their significance in indicating facies are discussed.
